What is Evaporative Dry Eye Disease?

One of the most common types of conditions afflicting the eyes, evaporative dry eye disease is an uncomfortable disorder of the eyes. The condition happens due to the blockage of the oil glands that line the corners of your eyelids. These oil glands, known as meibomian glands, are responsible for releasing oil that protects and covers the surface of your eye. These glands are also responsible for preventing your tears from drying out.

Tears are what help your eyes from becoming dry. Every time you blink, a little bit of tear fluid comes out from the oil glands at the corners of your eyelids. This fluid helps in washing away dust, germs, and other things that may get into your eye. When these meibomian glands do not work properly, your tears will dry out faster, making your eyes feel dry, itchy, and sore.

Evaporative dry eye or EDE is known to affect the elderly more, but it can occur to anyone at any age. It is more commonly known to affect women rather than men and also those with diabetes or having oily skin conditions.

Causes of Evaporative Dry Eye

Your tears are made up of oil, water, and mucus. Tears are responsible for forming a protective layer over your eye’s surface, making the surface of the eye appear smooth and also protecting your eye from infection. Tears need to be made up of these three things in a particular ratio so that it can help you see clearly. When your meibomian glands become blocked, the ratio of water, oil, and mucus become disturbed. Your tears then stop producing the correct quantity of oil that prevents them from evaporating. This causes Evaporative dry eye or EDE.

There are several factors that can lead to the blocking of your meibomian glands. If you are not blinking frequently, then you might develop a collection of debris at the corners of your eyelids which can block the glands. Concentrating too hard at a computer screen, driving for long distances and concentrating on the roads, and reading too much are all factors that can prevent you from blinking frequently. Some other factors that can cause blocking of the meibomian glands include:

  • Wearing contact lenses for a long period of time
  • Skin disorders such as psoriasis, face or scalp dermatitis, rosacea, etc.
  • Medications such as hormone replacement therapy, antihistamines, antidepressants, retinoids, decongestants, or even diuretics
  • Many illnesses such as diabetes, thyroid condition, Sjogren’s syndrome, rheumatoid arthritis, etc.
  • Allergies impacting the eyes
  • Some environmental toxins
  • Eye surgery
  • Vitamin A deficiency

Evaporative dry eye or EDE needs to be treated once identified as timely treatment can reverse the blockages in the meibomian glands. If Evaporative dry eye or EDE becomes chronic, then you will need ongoing treatment of the symptoms.

Home Remedies to Treat Evaporative Dry Eye Or EDE

While trying out any home remedy on your eyes, you have to remember that your eyelids are very delicate and it is important to be gentle while carrying out any remedy. Also, if your symptoms tend to persist, then consulting a doctor will be the best option.

  1. Massage Your Eyelids: Massaging your eyelids will help to release tears. You can also massage your eyes while having a warm compress on them. Simply press your fingertips gently on to the edges of your eyelids, just above the eyelashes. While you look up, roll your finger upward onto the lower eyelid. Then, roll your finger downward on the upper lid while looking down. Too much pressure will make your eyes feel worse, so be careful while massaging your eyes.
  2. Applying a Warm Compress: Take a face cloth or cotton pads and soak it in lukewarm water. Now close your eyes and hold the warm cloth above your eyes, onto your eyelids. Keep it on for five minutes and then repeat with the other eye. Doing this twice daily will make your eyes feel better. Once you experience some relief, you can do it only once a day. Applying heat to your eyes helps the glands produce more oil, melts away any crusting in the area that might have formed, and also makes the moisture from the glands flow more freely.
  3. Clean the Lash Line: Take a Q-tip or a warm washcloth to gently scrub along the eyelash line of both eyelids. This helps to remove any oil, bacteria, or other debris that might be blocking the gland openings. To clean, you can use either baby shampoo (watered down) or any gentle soap, making sure the product does not irritate your eyes. Doing this once a day will provide relief.
  4. Increase Your Consumption of Omega-3 Fatty Acid: Omega-3 fatty acids are known to improve the quality and consistency of the oil present in your eyes. Fish, flaxseed, walnuts, canola oil, etc., are good sources of omega-3 fatty acids.
